TO ALL WHOM I'l MAY CONOERN:

Be it known that I, G. W. BANA, of' Racine, in the county of Racine, andState of Wisconsin, have invented a new and useful 'Improvement inPadlocks; and I do hereby declare that the following is' a ful'l,`clear,and exact description thereof, which will enable others skilled in theart to make and use the same, reference being had to the accompanyingdrawings, forming part of this specification, in which- Figure l is afront view of my invention, the front plate of thecase being removed inorder to show the interior, as indicated by the line x fig. 1.

Figure 2, a vertical section of the same, taken in the line y y.

Similar letters of reference indicate like parts.

This invention relates to a new and improved padlock, and it consists ina peculiar construction of the same, whereby avery simple, economical,and secure lock, of the class specitied, is obtained, and one not liableto get out of .repair or `become deranged by use.

In the accompanying sheet of drawings, A represents the case of thepadlock, which may be of the usual form and construction, and having abow or shackle, B, attached by a screw or pivot-bolt, 1, at one end, theopposite. end being. provided with an eye, b, for the bolts of the' lockto pass through. These parts being of usual cons-trnctionf'do notrequire af special'description.

C C represent two bolts, which are portions of rings, and workl inAannular grooves, e c, within thelock-oase A, as shown clearly in g. 1.

The ends of these blts'are recessed or halved out a short distance fromtheir ends. The' halved portions lapping erich other, and having theirouter edges bevelled, are in a direction reverse to the other, as shownin iig. l, so that-the eye-end of the bow or shackle-B, .when pressedinto the lock, may force the bolts apar-t.

D Dare two bent levers, which work on fulcra d d, one lever, D, beingbehind a plate, E, within the lockcase, and the other, D', behind it;and F is a spring, the ends of which bear against the lower ends ofthebolts C C, anrl-has a tendency'to keep the halved ends of the boltsvinthe eye, 6, of the bow or shackle B, as will be fully understood byreferring to iig. 1-.

The boltsv C C are thrown back, and the lock unlocked, by actuating thelevers D D', through` the-medium I of the key G, the latter beingprovided with two bits, one to act against the lever D, at the outerside of plate E, and the other to act against the lever D behind saidplate, the latter having a key-hole made`in it, to allow the outer bitof the key-to pass through.

' By this arrangement, a very simple, economical, and secure padlock isobtained, and one not liable to geb out of repair.' y

Havingr thiis described my invention, I claim as new, and desire tosecure by Letters Patent,-

The two bolts C C, halvedl or recessed at one end, and lapped, one overthe other, and bevelled atV their outer edges, in connection with thebent leversfD D', plate E, and spring F, all arranged substantially asand for the purpose set forth,

G; W. DANA.
